l REGULATOR.

To all whom it may concern:

Be it known that I, RUDoLPHCoNnA-DER, a-citizen ot the United Sta-tes,residing at Erie, in the county foil Erie andState of Pennsylvania, haveinventedneiv and usey'ful Improvements in Regulators, ot which thefollowing is a specification.

This invention relates to regulators and consists 1n certainimprovements inthe construction thereof as will be hereinafter fullydescribed and pointed outlin the claims.

More particularly the invention relates to that type of regulator yWhichis actuated by a pressure' device, and the controlling valve of theregulator is usually so connected With either' a motor or compressor sothatthe action upon the controlling 4valve controls' the pressure. Withregulators of this type,

it isV desirable for different purposesto have `diner-ent actions of thecontrolling valve under the influence of changes of pressure on thepressure device. That is, tor some 1mi-poses, it is desirable to have apressure device which moves the valve gradually with an increase ofpressure on the pressure device. While for other purposes, itisdesirable to have Vthe controlling device move from one extreme to theother upon certain changes of pressure.

@ne of the objects of this invention is to arrangeI the pressure deviceso th'atit fmayv be adjusted to operate as desired in this r`espect.k n

The invention also involvesy an ment' in the controlling' valve. y

The invention isr illustrated in the accom-y improvepanying dravvings asfollovv's: i

Figure 1 shoivs a plan vievv, partly in section on the line 1-#1 in Fig.2. isa section on the line 2 2 in Fig. 1. FigQB 1sl a section on theline in Fig. l.; 1 marks thebo'dy' of the valve,`2` thedia'f phragm. Thediaphragm isr double in form so that there is an outlet, and inlettremit, both top andbott'omf. yFluid passes through the valve in eitherdirection by the ope'nings 1u and 1b. y

A bushing 3' is secured in one Wall ofthe diaphragm, and extends throughthe opposite Wall. It has radial openings 4 entending through itvbetween the Walls of the dia` phragin, and the Walls 2a connecting'thediaphragms are oi' suiiicient distancetrom the bushing 3 totorin apz'issaa'el'2b sothat the fluid can' enter or discharge" from cihe bushfing in au' directions. The valve 5 isor the Specification ofLetterslatent.

rotative type, and is arranged in the bushing, and has radial openings 6which are brought into' and out ot register With the openings e to openand close the valve. The

valve' is opened top and bottom so that the fluid passing the valve,enters or discharges both directions ofthe valve. 1n this Way,

the valve is given large capacity, and is andthis cover is secured tothe body by the screiv 8. A; gland 9 is arranged in the cover 7, and thevalve stem 10 extends through this gland. 'The lower end of the valve issquared at 10a, and extends into a squared socket 'LL in thetop ot thevalve. This is a comparatively loose iit so' that the valve can readilyiind its position Without binding ot the parts. The upper end of thestem has the squared end 11 on which a crank 12is arranged. Vrlhe crankhas the throated end 13.

The pressure device is as iolloivs: A cylinder 14 is secured on thebracket l5v extending from the 'cover 7, and is securedA thereon by'means ot' the screyvsl. Fluid is pumped to theV cylinder through a pipe17, and.v of course, leads from some supply which itis desired tocontrol, ordinarily a receiver. A piston 1S is arranged in the cylinder,and this operates upon the pitman 19, the inner end of which' isarranged in a socket in the piston. rlhe pitman has the throated end 20,and the links 21 are arrangedeach side oit the throated end andconnected there With by thepin 22. The links 21 are also connected to anear 23' extending from the cylinder bymeans of a pin 24; The pitman'engages a lever 25 and is provided With a roll `192L` between the armsof the throatedk between the -ears v26 on thev cylinder vby means of apin 27. It has the throated end 28 between the arms of which arranged a`trunnion 29. A link 30 secured between `the arms fo'rrns thethroatedfend 13 of the;

crank by means oi a pin 31. The opposite end ot the link 30 isscrewthreaded andy extends through the trunnion 29 and secured tothetrunnion by' means of the nuts 32, on each side ofthe trunnion. By'means f these, the link am be adjusted to give the valve any desiredinitial position. The eX- tension 83 is arranged on the lever25, and iSconnected with a head 34 by means of a pin 36, the head 34 having thearms 35 extending each side of the extension 33. AV pin 37 is screwedinto the head and extends through the screw 38. The screw 3S is arrangedin a stud or post 39 extending from the cylinder 14. rFhe end ottherod37 is screw thread-,' ed and a nut 40 is screwed onto the rod againstthe screwSS, and by means of this Y it nut, the initial position of therod may be adjusted, and the adjustment locked by the jam nut 4l. Aspring-,42 is tensioned between the'head 84, andl the screw 38. Any

' Y desired tension may be given to thisspring by operating'the screw38. It'will be observed that moves outwardly as the'piston moves under'the influence of the fluid inV the cylinder as Ythe pitman 19 y theouter end of the pitman operatingV on .tlielever and cam 25Va iscontrolled by the links 2l, and swung to a circular path with f the pin24 as a center. In the beginning ofl this movement, the path of theouter end of the pitman is about in line with the pitman, and the end`of the pitman .is nearest Ythe pivot formed by the pin '27 of thelever25. YAs the pitman Vmoves outwardly, however, its path of movement isdeflected more and more vfrom a direction in line with that of thepiston; and'V consequently, there is a greater ratio ofV movementl ofthepitman along the lever 25 with va given'endwise movement of the pitmanas the pitman y reaches its outward positions.

In the norn mal use of the'regulator but a small part of the possibletravel of the piston is neces-. sary. Consequently, the pitman may bead-k justed soras to. havean initial position as ,shown4 in Fig. `1 inywhich case the j ratioV of increase in leverage by reason of f thevmoving of the end of the pitman awayv from the pivot of the Vlever 25 isbut slight. It 1t is desired to have this leverage increase r veryrapidly'so that, for instance, if itis Vdesired to have .the valvecompletely close when the pressure on the piston reaches a point thatwill start it, this may be accomplished by adjusting the rod 37 by meansofthe screw`4l to a position which will bring thel initial positionvo-the'end of ythe pitman engaging the lever 25 outwardly from thatshownin Fig. 1 so that-the continued movement of the pitman will'bemorev abruptly deflected from the lineof movement of the piston so thatvwith a given movement of the piston, the movement of the end of thepitman relatively to the pivot 27 is very rapid,`and consequently, theleverage will increase more rapidly than the strengthof the spring byreason of' its compression. Inthis way, any variation along ,this `line;may beisecuredzthat may be desired simply by adjusting the initialposition of the end of the pitman. After the leverand pitman areadjusted to the position desired for them, the link 30 may be adjustedso as to give the proper initial .position to the valve, and the screw38 may be adjusted to adjust theV tension of the spring 42. Of

course where the screw 38`is so adjusted,v

the nut 40 should be adjustedfto compensate for thediiference inposition oic the screw.rk
